and be only the second ever world champion on both two and four wheels.
lastnight Lewis Hamilton left fans guessing by tweeting picture of himself walking towards a bike with the message 'Announcement coming tomorrow...'
And now the announcement is here. As anticipated, it's a not a career switch to bikes but a special Lewis Hamilton edition of the MV Agusta F4, called the LH44 - because only 44 are to be made.
The F1 star ended the suspense with a follow-up tweet this afternoon saying: 'Proud to work with MV Agusta on an awesome Superbike, the F4 LH44!'
The limited-edition gets special features including an Öhlins shock and upside-down fork in black instead of the usual gold colour.
